초록

A new Korean Meteorological Administration (KMA) airborne measurement platform has been established for regular observations for scientific purpose over South Korea since late 2017. CRDS G-2401m analyzer mounted on the King Air 350HW was used to continuous measurement of CO2, CH4 and CO mole fraction. The total uncertainty of measurements was estimated to be 0.07 ppm for CO2, 0.5 ppb for CH4, and 4.2 ppb for CO by combination of instrument precision, repeatability test simulated in-flight condition and water vapor correction uncertainty. The airborne vertical profile measurements were performed at a regional Global Atmosphere Watch (GAW) Anmyeon-do (AMY) station that belongs to the Total Carbon Column Observing Network (TCCON) and provides concurrent observations to the Greenhouse Gases Observing Satellite (GOSAT) overpasses. The vertical profile of CO2 shows clear altitude gradient, while the CH4 shows non-homogenous pattern in the free troposphere over Anmyeon-do. Vertically averaged CO2 at the altitude between 1.5 and 8.0km are lower than AMY surface background value about 7 ppm but higher than that observed in free troposphere of western pacific region about 4 ppm, respectively. CH4 shows lower level than those from ground GAW stations, comparable with flask airborne data that was taken in the western pacific region. Furthermore, this study shows that the combination of CH4 distribution in free troposphere and trajectory analysis, taking account of convective mixing, is a useful tool in investigating CH4 transport processes from tropical region to Korean region in winter season.
